Title: Improvements relating to cylinder printing machines
Inventor: SCHUENEMANN HANS BERNHARD
IPC: B41F3/58
Filed: 1958-01-24
Abstract: 878,346. Printing machines. SCHNELLPRESSENFABRIK KOENIG & BAUER A. G. Jan. 24, 1958, No. 2538/58. Class 100(2) A cylinder printing machine with a uniformly rotating impression cylinder and a type-bed having a toothed rack which travels faster during its non-printing stroke than during its printing stroke has a fixed drive-wheel in constant mesh with the toothed rack of the type-bed, the printing and non-printing strokes being effected by one of two different gear mechanisms alternately co-operating, directly or indirectly, with toothed means on the drive wheel shaft such that in the printing stroke the type-bed attains its highest speed in a shorter time and with less travel than during the non-printing stroke. As shown, a uniformly driven shaft 2, Fig. 1, drives an impression cylinder 20 through gearing. A toothed segment 5 on the shaft 2 has rollers 3 and 4 engageable with flanks 6 and 9 respectively of a sector secured to a shaft 7 which drives the bed through a rack and pinion 1. The roller 3 rotates the shaft 7 through 45 degrees to permit engagement of segment 5 with a driving wheel 8 on the shaft 7 to drive the bed on its printing stroke to the right, the roller 4 subsequently braking the shaft 7 by engagement with the flank 9. When the shaft 7 is stationary, a roller-10 on a toothed segment 14 fixed to the shaft 11 engages a flank 16 of a fork member on a shaft 19, thereby causing a toothed segment 13 to drive the wheel 8 in the direction opposite to that previous. The bed is thus driven through the pinion 1 on its quick non-printing return stroke. A roller 17 engaging the other flank 16 brakes the quick return motion of the bed ready for the next printing stroke. In a modification, Fig. 2, a shaft 21 carries a gear sector 22 having rollers 23, 24 which co-operate with flanks 28, 29 of a member on a shaft 27. The sector 22 carries a roller 25 co-operating with a rocker arm 26 of a toothed sector 32 on a shaft 33. The bed is accelerated during its printing stroke by the roller 23 engaging the flank 28, then moved uniformly by the sector 22 engaging a pinion 34 on shaft 27, and is finally retarded by the roller 24 engaging the flank 29. The bed is returned by the roller 25 lifting the rocker arm 26 and sector 32 which rotates the pinion 34. In a further modification Figs. 3 and 4 (not shown) the bed is drivcn by an oscillating pinion driven alternately by two pinions on shafts driven in opposite directions.

Title: Improvements in or relating to change speed gear mechanism, more particularly for vehicles
IPC: F16D25/065
Filed: 1943-02-18
Abstract: 564,317. Variable-speed gearing. BALLAMY, L. M., SHEEPSHANKS, R. H., and G.B. (NOTTINGHAM), Ltd. Feb. 18, 1943, No. 2744. [Class 80 (ii)] [Also in Group XXIX] In variable-speed gearing in which speed changes are effected by coupling gear-wheels to a driven shaft by hydraulically-actuated friction clutches, each clutch comprises a drum with an internal cylindrical surface against which an arcuate friction shoe is pressed by means of a hydraulic piston and cylinder mechanism carried by a support fixed to the shaft. As shown, a driving crank-shaft 11 has gears 45, 47, 50, meshing with gears 44, 48, 52, formed on cylindrical drums 41, 49, 53, freely mounted on a driven shaft 25. The inside of each drum co-operates with an arcuate friction shoe. As shown, for the drum 41, Fig. 2, a pair of shoes 72, 73 are pivoted at 74, 75 to a block 58 fixed to the shaft 25 and are forced outwardly to engage the clutch by levers 65, 66 connected to pistons 62 acted on by oil pressure in cylinders 60 formed in the block 58. In the case of the drums 49, 53, only a single shoe 88 is used and the piston which acts directly against an inclined surface 87, Fig. 3 (not shown), of the shoe is in the form of a ball 85. The pistons are loose fitting so that they are effective only while fluid pressure is being supplied thereto. The oil is supplied by a lubricating pump 22 via a pipe 24 and a duct 93 in the shaft 25, the distribution is controlled by an axially slidable valve 95, the interior of which is connected to the duct 93. A port 118 may register with a duct 119 to supply oil to the cylinder 120 of the clutch drum 53, and a port 115 may register with ports 83, 116, to actuate the clutch drums 41, 49. The valve 95 is adjusted axially by rack-and-pinion gearing 98, 99. When the valve 95 is in a neutral position so that the clutches are cut off from the oil supply, any oil in the clutch cylinders leaks away. A valve 123, Fig. 4, may be provided in the duct 93 to ensure that pressure fluid is supplied to the valve 95 only while one of the clutches is in operation. The valve 123 is held closed by a spring 124, and is opened by cam projections 126, 127, 128 on the valve 95 when the latter is in one of the clutch-actuating positions. In the latter positions, the valve 95 is held positioned by a spring-pressed ball 132 engaging a recess between a pair of the cam projections.

Abstract: 414,117. Yeast. INDUSTRIKEMISKA AKTIEBOLAGET, 11, Blasieholmstorg, Stockholm. Jan. 30, 1933, No. 2875. Convention date, Jan. 30, 1932. [Class 14 (ii).] In the manufacture of yeast, the fermenting liquid is caused to flow in a closed cycle from the fermentation vessel 1 (Fig. 1), over an aerating device 2, and back to the vessel 1, air or an oxygen-containing gas is forced through liquid in the aerating device, and the excess of air or other gas is led off so as to prevent it taking part in the circulation of the liquid. The liquid is delivered by a pump 4 through pipes 3 and 5 to the channel 6 from which it spreads in a thin layer over a perforated screen 7 provided with overflows 8<a> and 8b, whereby it is returned through pipes 9<a> and 9<b> to the vessel 1. Below the screen 7 the mouth of a pipe 14 coming from a fan 15 admits air or gas at a low pressure. To keep the wort in motion a pump 10 is provided which draws wort from the vessel 1 through a pipe 11, and returns it into the vessel at a higher point through one of the pipes 12 or 13 or both. The Specification as open to inspection under Sect. 91 comprises also the form of apparatus shown in Fig. 3 (Cancelled) wherein an aerating device 2 floating in the vessel 1 is provided with a perforated screen 7. The device is loaded so that the screen is just above the level of the water, and is guided by telescopic tubes 14. Compressed air is introduced below the screen 7 through a pipe 15, for example by means of a fan. A propeller 16 driven by a motor 17 forces the fermenting liquid upwards so that it flows over the perforated screen 7 back into the outer portion of the vessel 1. A guide 18 on the device 2 prevents the depth of liquid on the screen from exceeding the permissible limit. This subject-matter does not appear in the Specification as accepted.
